[Bug] instreamer does not work remotely

[qku]

Version

current main

What is affected by the bug?

• Windows 10
• current main
• data instream dummy
• wavemeter instreamer (under development)

When does the bug occur?

When calling read_data() of a data instreamer remotely. Other methods like start_stream() work fine.

How do we replicate the issue?

1. activate data instream dummy or wavemeter instreamer and allow remote
2. connect to the module remotely
3. start the stream via the console
4. call read_data()

Expected behavior

read_data() should return recent samples from the instreamer
